如何在文件夹的日期范围之间检查和获取zip文件，并使用C＃winforms将其写入组合框 [英] How to check and get zip files between date range from a folder and write it into combobox using C# winforms

问题描述

你好!!!

我需要一些C＃winforms的帮助。我首先想要使用Datetimepicker来设置日期范围，在该日期范围内我可以每周检查文件夹上是否有新的zip文件。如果是这样的话我想在我的组合框中获得这个新的zipfile（只有文件名）。之后我想在datagridview上获取zip文件的所有条目。

我该怎么做？有人可以帮我提出任何想法吗？



非常感谢!!!



我是什么尝试过：

Hello!!!
i need some help in C# winforms. I firstly want to use a Datetimepicker to set the date range in which l could weekly check if there is a new zip file on the folder. if that's the case i want to get this new zipfile (only the filename) in my combobox. And after i'm suppose to get all entries of the zip file on a datagridview.
How can i do this? can someone help me with any ideas?

Many thanks!!!

What I have tried:

// Show the OpenFileDialog.
        DialogResult result = ofd.ShowDialog();
        if (result == DialogResult.OK)
        {
            string fullPath = ofd.FileName;
            string directory;
            directory = fullPath.Substring(0, fullPath.LastIndexOf('\\'));

            textBox1.Text = directory;

            DateTime.Now.ToString("yyyyMMdd"); // ??? i don't know how i can query the date range so that it will be considered in my code

            if (File.Exists(fullPath))
            {
                string[] AllZipFiles = Directory.GetFiles(directory,"*.zip",SearchOption.AllDirectories); // Get all files from the folder

                foreach (string zipfile in AllZipFiles)
                {
                    this.comboBox1.Items.Add(zipfile); // it' working but with all the fullpath, but i only want to get the filename like test.zip
                }

            }
            else
                MessageBox.Show("There is not Zip File in this Folder");
        }

推荐答案

试试这个：

Try this:

string path = @"D:\Audiobooks"; //change initial path to your needs
string filter = "*.zip";
DateTime startdate = new DateTime(2012,1,1); //change dates to your needs
DateTime enddate = new DateTime(2016,12,31);

List<string> files = Directory.EnumerateFiles(path, filter, SearchOption.AllDirectories)
	.Where(x=>File.GetLastWriteTime(x)>=startdate && File.GetLastWriteTime(x)<=enddate)
	.Select(x=>Path.GetFileName(x))
	.ToList();

foreach(string zipfile in files)
{
    combobox1.Items.Add(zipfile);
}

详情请见：

Directory.EnumerateFiles方法（String，String，SearchOption）（System.IO） [ ^ ]

File.GetLastWriteTime Method（String ）（System.IO） [ ^ ]

Path.GetFileName Method（String）（System.IO） [ ^ ]
